To @ZZ whom it may concern:

Be it known that I, ANNA HOEFER, (ne

Rieger) a subject of the Emperor of Germany, residing at Wahlershausen, near Kassel, in the Province of Hesse-Nassau, Kingdom of Prussia, Germany, have invented certain new and useful Improvements in Looking Devices for Pots andithe Like, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to a locking device for pots and the like, which device is adapted to press the cover on the riin of the pot and the like and includes a handle for carrying about the vessel.

I will now proceed to describe my invention with reference to the accompanying drawings, in which- Figure 1 is a vertical section through a potprovided with a locking device on the line A B in Fig-2. .Fig. 2 is a plan of the same. Fig. 3 is a plan of another pot with a modified locking device; and Fig. 4 is a vertical section similar to Fig. l, the locking device being partly the same as in Figs. 1 and 2 and partly the same as in Fig. 3.

Similar letters of reference refer to similar parts throughout the several views.

In Figs. I and 2 a pot a is shown as provided with a rounded-off rim g and two turnable hooks f f. The cover l) may be made in a shape shown, so as to fit close to the rim g, and is provided with a handle c. The two hooks f f are arranged i' or pressing the cover b on the rim g and may in this state be on a level with the top face of the handle c, as is shown at Fig. l. A locking spring d is mounted to turn on the handle c in the horizontal plane around a pin. This spring d is arranged to bear on the free ends of the two hooks ff, and thus to close the pot a. To prevent it from shifting inadvertently, 'its two longitudinal edges are preferably bent a little downward, so as to inclose the free ends of the two hooks ff. It will be seen that the pot a is thus tightly closed. If so preferred, a packing-ring (not shown) of any suitable and known material may be fastened on thel inside of the annular recess of the cover b, in which the rim g engages for hermetically closing the pot. By means of the handle c the pot can be carriedabout. When it is desired to open the pot a, all that is required is to turn the spring d off the ends of the two hooks f f and to turn aside the latter, after which the cover b can be taken off. It is immaterial in which known manner the two hooks f f are pivotally connected with the pot 0,. The pot a, may be provided with two stationary hooks or tillers h 7L, (see Fig. 3 and the right part of Fig. 4,) and the turnable spring d is in this case so much lengthened as to be able to engage beneath the upper parts of the tillers h h from either side. The spring d and the two tillers 71, hshould be so arranged as to press the cover b on the rim g of the pot, it being immaterial whether the spring d be made straight, as in Fig. 4 on the riOht, or bent. The part of the spring d within the rim of the cover b may be iiat, or it may be made concave on thelower side by bending its two longitudinal edges a little downward. (See Fig. 4.) In this case the cover b is preferably so placed on the pot a that its handle c is in the same longitudinal plane as the spring d after the latter has been turned to engage beneath the two tillers 7o h. (See Fig. 3.) Then the spring d-will be prevented from shifting inadvertently, since its downwardly-b ent longitudinal edges elasticallybear on the corresponding edges of the handle c. The manner of operating this locking device is evident after the above explanations.

The lockinO device may be made partly as in Figs. 1 andD 2 and partly as in Fig. 3 in the manner shown at Fig. 4, which requires no further explanation. The pot a may be of any known kind, and also the cover b, the essential point being that the cover b can be pressed on the rim g of the pot and the like by means of the locking device. The locking device may be varied without departing from the spirit of my invention.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination with a vessel and the cover therefor designed to seat upon the rim thereof, of a handle for the cover, two clips attached respectively upon opposite sides of the vessel to the exterior of the same a distance below the rim thereof and provided with angular portions disposed in substantially horizontal planes above the top of the rim and a spring member secured to the handle and designed to engage the angular portion of the clips for holding the cover onto the vessel, substantially as described.

2. The combination with a vessel and a cover therefor having its rim en aging the edge of the vessel, of a clip pivote to the exterior of the vessel below the edge thereof and provided with an angular portion designed to IIO engage the rim of the cover and extend inwardly beyond said rim and a spring-plate secured to the cover designed to bear down upon said inwardly-etending end of the clip for holding the rim of the cover into engagement with the edge of the vessel, substantially as described.

3. The combination With a vessel, of a dished cover having,l a vertical edge Wall terminating in a substantially horizontally-dis posed rim designed to embrace the edge of the vessel, a handle secured to the central part of the cover having its top in substantially the plane of said rim, clips secured to the side of the vessel havingl horizontally-disposed parts and a plate pivoted to the top of the handle designed to engage the horizontally-disposed parts of the clip, substantially as described.

pot and the like, a second hook fastened on said pot and the like opposite to said hook, and a spring mounted to turn on said handle and adapted to lock the 'free ends ofsaid hooks and to engage beneath said second hook for pressing said eoverat the other side on said pot and the like.

In testimony whereof' l have aflixed my signature in presence of tWo Witnesses.
